Hard Out There for a Cop, Thanks to Three 6 Mafia

A wild brawl broke out at a Three 6 Mafia concert last night in West Hollywood. Body count -- two arrested and a woman wheeled out on a gurney -- and it wasn't Britney!

The fight erupted after the rappers finished their set at the House of Blues. The men in blue (they actually wear tan uniforms but men in tan makes no sense) -- aka L.A. County Sheriffs deputies -- swarmed the joint, inside and out.
